Problems solved by technology

[0002] In the field of mineral processing engineering, wettability is one of the most important properties that determine the selectivity of minerals. Wetting angle method and microcalorimetry are usually used, but the determination process of these two methods is cumbersome and can only measure a little bit of minerals. Due to the inhomogeneity of the mineral surface and the possible contamination, there is a certain degree of randomness in the results. At the same time, it has high requirements for experimental operations and sample preparation, and the obtained results are also an indirect characterization of wettability. There may be some deviation in the measurement results

Abstract

The invention discloses a mineral particle wettability measuring device and a measuring method thereof, which comprise a cylindrical container with openings at both ends, a hopper, a hollow cover, a humidity sensor and an atomizer. The upper end of the device is sealed with a feeding hopper in the middle, and the humidity sensor is installed at the bottom of the inner side of the hollow cover. It rests on the base with a bracket installed in the middle. The invention directly characterizes the wettability of minerals through equal volume and equal particle size mineral water absorption, which can simulate the contact process of mineral particle phase and water phase in the flotation process in the mineral processing process, has the advantages of simple sample preparation, and can directly reflect the mineral wetting The characteristic of wetting tendency provides guidance for later flotation separation.

Description

technical field [0001] The invention relates to a mineral particle wettability measurement device and a measurement method thereof, belonging to the technical field of mineral wettability measurement equipment. Background technique [0002] In the field of mineral processing engineering, wettability is one of the most important properties that determine the selectivity of minerals. Wetting angle method and microcalorimetry are usually used, but the determination process of these two methods is cumbersome and can only measure a little bit of minerals.
